Java and Javascript bug

On input "cdddcdadd" the Java and Javascript implementations give wrong grammar as outputs

I hit this bug too. I think it's related to this comment in the code:

            # This is to deal with trigrams, where we only record the second
            # pair of the overlapping bigrams. When we delete the second pair,
            # we insert the first pair into the hash table so that we don't
            # forget about it.  e.g. abbbabcbb

My test case is "abbbabcbb" but it fails the same way. Did you find the solution?

There's a proposed fix in PR #7
